The battery in my 520 is getting progressively worse, but it has been hammered since I got it.
It looks like the OE battery is a CS-JR520SL at 3.7V and 1000mAh / 3.79Wh, would there be any harm in fitting one with a greater capacity, say a 1800mAh / 6.66Wh like the ones used in HP handheld PC's to extend the battery life?

If you try it, please report back! (With disassembly pictures.)

Size might be an issue. Slightly thicker
Changed my 705s battery this year after many years service
